DESCRIPTION

The instant invention concerns the removal of hydrocarbons from solid materials, such as from drill cuttings in drilling mud, which contain hydrocarbons. During rotary drilling operations, a volume of subterraneous material encountered is removed to provide the well bore. This material is generally referred to as drill cuttings. The cuttings are usually mixed with the drilling fluid used and any water or hydrocarbons encountered subterraneously during drilling operations.

In a typical drilling operation, the cuttings are separated from the drilling fluid by way of a shale shaker. The recovered drilling fluid is usually recirculated for further use in the drilling operation. The cuttings removed by the shale shaker are not only coated with but contain a mixture of water, hydrocarbons, and constituents of the drilling fluid. In some cases, the drilling fluid itself may contain hydrocarbons which contribute to the contamination of the drill cuttings.

The disposal of the drill cuttings and drilling mud is a complex environmental problem. Drill cuttings contain not only the residual drilling mud product that would contaminate the surrounding environment, but may also contain oil and other waste that is particularly hazardous to the environment, especially when drilling in a marine environment.

In addition to shakers, various methods for removing hydrocarbons and contaminants from drill cuttings and drilling fluids have been employed. However, the high costs and plant construction complexity, significant energy waste, limited safety, especially when operating offshore, and low efficiency have rendered such previous methods disadvantageous for extraction of hydrocarbons.

Accordingly, there exists a continuing need for methods and systems for extracting hydrocarbons from drill cuttings.

The methods of treating solids described herein may, in one embodiment, comprise delivering a contaminated energetic material to a heat source or heat chamber; subjecting the contaminated energetic material to a temperature sufficient to vaporize substantially all of the diesel fuel present in the contaminated energetic material; and condensing a portion of the diesel fuel from the contaminated energetic material.

Referring to FIG. 2( a), incoming materials 8 are supplied by roll off box, rail, truck or other form of transportation to incoming materials handling area 10. In one embodiment, incoming materials are wet solids contaminated with hydrocarbons such as oilfield waste, drilling mud, drill cuttings, contaminated soil or sludge. Incoming materials 8 are then moved from incoming materials handling area 10 to receiving pit 20 by receiving pit supply line 15. In an alternate embodiment, incoming materials 8 are loaded directly into receiving pit 20. Material from receiving pit 20 is then supplied by feed pit supply line 25 to feed pit 30. Feed pit 30 provides material to heat source 50 by way of a conveyance system. Various embodiments of the feed conveyance system will include any of the following, alone, or in combination: conveyers including but not limited to screw, belt or spiral conveyors or pumps including but not limited to centrifugal, diaphragm, positive displacement and screw pumps. In an embodiment of the invention, the conveyor system includes a feed line 35, concrete pump 40, and heat source feed line 45. In one embodiment, feed line 35 is a horizontal auger.

The heat source 50 may take many forms including a rotary drum and rotary or other indirect-heated dryers. The supply of heat to the heat source 50 may include but is not limited to the combustion of hydrocarbons such as natural gas, liquid petroleum gas, petroleum liquids, hot combustion gases from other sources (flares, engines, or heaters), steam, or electricity. The operating temperatures of heat source 50 may be selected based on a reference compound either theoretically or actually selected for removal, in one embodiment the operating temperatures may be greater than or equal to the boiling point of the first reference compound. In one embodiment, the heat source 50 is a calciner that uses the indirect heat of the calcining process to drive of all of the volatile components supplied by heat source feed line 45. In one embodiment, the calciner is set up to evaporate diesel hydrocarbons and has three temperature zone ranges: calciner zone one at 700° F. to 800° F., calciner zone two at 800° F. to 1000° F. and calciner zone three at 1000° F. Catchier zone one raises the temperature of the feed material to vaporize most of the water content, calciner zone two begins the vaporization of the hydrocarbon material, and calciner zone three removes any hydrocarbon compounds with a higher boiling point. These volatile components leave heat source 50 by vapor line 53. Solid residue from heat source 50 is removed by a conveyance system to solids residue vessel 80. This conveyance system is of a type capable of moving dry hot solids, including but not limited to screw, belt, or spiral conveyors. In one embodiment, this conveyance system includes a hood 55 to direct the solid residues, a horizontal auger 60 and inclined auger 70 which ultimately transport the solid residues from heat source 50 to solids residue vessel 80. In an alternate embodiment horizontal auger 60 is a trough auger and incline auger 70 is a tube auger.

Incline auger 70 conveys solid residue to solids residue vessel 80. Solids residue vessel 80 can be any vessel capable of housing solid residues conveyed from heat source 50. In one embodiment, a solids residue vessel vent 83 is attached to solids residue vessel 80. In one embodiment, solids residue vessel vent 83 is a fan driven vent that maintains a negative pressure to aid in air flow within solids residue vessel 80. In another embodiment, solids residue vessel vent 83 is a vent with a water scrubber. Solid residues are transported from solids residue vessel 80 to disposal 90 by solids residue conveyor 85. Solids residue conveyor 85 can include, but is not limited to, any of the following, alone, or in combination: roil off box, fork lift, truck or other form of transportation or conveyance for dry materials. From disposal 90, the solid residue can be transported to a landfill or combined with additional drill cuttings to solidify the drill cuttings for disposal. In one embodiment, the hydrocarbon content in the solid residue is in the range of 1500 to 5000 parts per million (ppm).

Referring now to FIG. 2( b) of the drawings, vapor from the heat source 50 is in fluid communication with the diesel condenser 120 via vapor line 53. Vapors exiting the heat source 50 via vapor line 53 may be condensed indirectly via a heat exchanger or directly by contact with a cool liquid. Condensation through direct contact may be accomplished by one of several methods including scrubbers with spray nozzles, packed or trayed columns, or dispersion of the vapor within a column of cooler liquid. In one embodiment, condensation occurs through direct contact of the heat source vapors with a circulating hydrocarbon stream. In one embodiment, diesel condenser 120 condenses the hydrocarbon vapor directly by contact with a cooled liquid diesel stream. Diesel condenser 120 also collects diesel and drains to sludge settling and separation box 140 by line to sludge settling 125. Sludge settling and separation tank 140 separates diesel from sludge removing the sludge through sludge removal line to landfill 146 and supplies diesel to diesel storage tank 160 through sludge separator line to diesel storage 142. Diesel condenser 120 is supplied with cooled liquid diesel for the condensing of diesel vapors from diesel storage tank 160 by diesel condenser spray feed line 165. Diesel condenser 120 also directly supplies diesel to diesel storage tank 160 through condensed diesel line to diesel storage 128. A stream of un-condensed gas and vapors containing water vapor leaves diesel condenser 120 through water vapor exhaust line 123 and travels to water condenser system 180. Remaining water and condensable matter delivered through water vapor exhaust line 123 are condensed in water condenser system 180. Sludge and debris from the condensing process are removed from water condenser system 180 by way of sludge removal line from water condenser system 184 and condensed water line to water storage 186 carries the remaining condensed water from water condenser system 180 to water storage tank 200. Water storage tank 200 vents to the atmosphere through vent to atmosphere 204 and drains through water washout for disposal 206. Vent to atmosphere 204 contains a fan which creates a negative flow or suction which aids in pulling the volatile vapors released from heat source 50 through the system. Water from water storage tank 200 is recirculated by water supply line 210 and water condenser bypass line 212. A portion of the water traveling through water supply line 210 is routed to water condenser system 180 by way of water condenser liquid water feed line 214.

Referring now to an alternate embodiment in FIG. 3, vapor from the heat source 50 is in fluid communication with the diesel trap tank 220 via vapor line 53. Vapors exiting the heat source 50 via vapor line 53 may be condensed indirectly via a heat exchanger or directly by contact with a cool liquid. The vapors are indirectly condensed by exposure to ambient temperatures sufficient to condense substantially all of the diesel vapor in diesel trap tank 220. The condensed diesel vapors are then transported to sludge settling and separation tank 240 through line to sludge settling 225. In one embodiment, a pump is used to transport the condensed vapors from diesel trap tank 220 to sludge settling and separation tank 240. Sludge settling and separation tank 240 separates diesel from sludge removing the sludge through sludge removal line to landfill 246 and supplies diesel to diesel storage tank 260 through sludge separator line to diesel storage 242. Condensed diesel exits diesel storage tank 260 through diesel removal to sales 265. Excess sludge in diesel storage tank 260 is removed through sludge removal line from diesel storage to landfill 263.

A stream of un-condensed gas and vapors containing water vapor leaves diesel trap tank 220 through water vapor exhaust line 223 and travels to Water condenser system 280. Condensed liquids from diesel trap tank 220 are intermittently sprayed into water vapor exhaust line 223 to aid in the condensing process. Remaining water and condensable matter delivered through water vapor exhaust line 223 are condensed in water condenser system 280. Sludge and debris from the condensing process are removed from water condenser system 280 by way of sludge removal line from water condenser system 284 and condensed water line to water storage 286 carries the remaining condensed water from water condenser system 280 to water storage tank 300. Water storage tank 300 vents to the atmosphere through vent to atmosphere 304 and drains through water washout for disposal 306. Vent to atmosphere 304 contains a fan which creates a negative flow or suction which aids in pulling the volatile vapors released from heat source 50 through the system. Water from water storage tank 300 is recirculated by water supply line 310 and water condenser bypass line 312. A portion of the water traveling through water supply line 310 is routed to water condenser system 280 by way of water condenser liquid water feed line 314.

In one embodiment, contaminated solids are fed into the feed pit 30 at a rate of one ton per hour. The contaminated solids have a hydrocarbon concentration of 15% by weight, water concentration of 20% by weight, and solids content of 65%. In this example, the hydrocarbon is primarily diesel. The materials are pumped through feed line 35 to heat source 50 by concrete pump 40 so that the hydrocarbons can be vaporized and removed through evaporation. In one embodiment, heat source 50 is a rotary catchier which is separated into three heat zones that heat the material through the ambient temperatures it provides. Upon entering the rotary catchier of heat source 50, the solid materials reach calciner zone one and are subjected to an externally measured temperature range of 850° F. to 950° F. The temperatures of catchier zone one are sufficient to vaporize substantially all of the water in the contaminated solids. Continuing through the catchier, the materials arrive to catchier zone two and are subjected to an externally measured temperature range of 1000° F. to 1100° F., vaporizing most of the hydrocarbons in the contaminated solids. The remaining material continues down the calciner to calciner zone three where an externally measured temperature of 950° F. to 1000° F. is maintained to vaporize the final small amount of the hydrocarbon that, remains. The solid residues exit the calciner and are transported to solids residue vessel 80 via a conveyance system. Through this calcining process, all of the water is vaporized. Furthermore, substantially all of the hydrocarbon is vaporized. The hydrocarbon content is reduced from 15% by weight in the contaminated material to a range of 1500 to 4500 parts per million (PPM) in the solid residue. This marks a total removal of hydrocarbons in the range of 99.9965% to 99.9985%. From solids residue vessel 80, the cleansed solid residues are conveyed to disposal 90.

In order to adequately pull the volatile vapors from the calciner through the condensing zones, the entire operation is maintained at a negative pressure measured in a range of −02 to −0.6 inches of water column. The volatile vapors are transported from the heat source 50 calciner to diesel condenser 120 through vapor line 53. In one embodiment, diesel condenser 120 is a scrubber condenser which condenses the diesel vapors by spraying them with a stream of cooled vapors that are recirculated from a diesel storage tank 160. In an alternate embodiment, diesel is condensed indirectly via a heat exchanger instead of directly through contact with cool liquid diesel. From the diesel condenser, the condensed diesel is transported to the diesel storage tank. The condensed diesel is collected, stored, and eventually sold for reuse. The uncondensed water vapors exit diesel condenser and are transported to water condenser system via water vapor exhaust line 123. The water vapor system is a scrubber condenser which directly condenses the water vapors by spraying cooled liquid water into the vapors. The condensed water is transported to water storage tank 200. At least a portion of the cool condensed water in water storage tank 200 is recirculated into water condenser system to be sprayed by the scrubber condenser. Through this process a portion of the water is condensed and recovered while the balance of the water is vented to the atmosphere as saturated gas. In one embodiment, cooled liquids are sprayed into water exhaust line in order to aid in the condensing of the water vapor.
